In this fun clip from Nature Cat: Ocean Commotion, Nature Dog and Sputnik form an unlikely alliance to rescue Mr. Chewinsky and in the process, they find out whether it’s possible to travel around the world using only the ocean currents.

In this exciting clip from Nature Cat: Ocean Commotion, Nature Cat and his friends try to catch up to Hal's favorite toy, Mr. Chewinsky. Along the way, they learn about currents and how all rivers eventually lead to the ocean.

Three friends record the many different sounds they hear in their neighborhood, in this video from PLUM LANDING. By walking and quietly observing, they notice a range of sounds, from nature sounds like birdcalls to sounds made by people, like a jogger’s footsteps and the notes from a musician’s saxophone.

A group of friends explores an urban forest with a U.S. Forest Service ranger, in this media gallery from PLUM LANDING. They see how the network of trees and other green spaces creates a forest in the city, providing a habitat for birds, squirrels, and other forms of wildlife. They also learn how forests are like cities for animals, where many things live on trees, from the top of the canopy to the roots in the ground. They even find things living in the dead trees on the forest floor!

A group of students participate in a scavenger hunt activity to explore and document biodiversity in an urban park, in this video from PLUM LANDING. As they walk around in search of various plants and animals, they also find litter and talk about its negative impact on animals.

Plum sends Brad and Clem on a mission to observe a group of ants, in this animated video from PLUM LANDING. Brad describes the ants as “awesome monster creatures” that start an ant war with another colony. But Clem sees the ants working together as a team to gather food. So what are ants: scary creatures or cute, friendly insects or a little bit of both?

In this episode of Sid the Science Kid, Sid and his friends lean that dirt is really important to the Earth because it helps things grow, and it's also filled with tiny rocks, pieces of leaves, and even living things like bugs and worms!

Players strive to create a balanced mountain ecosystem in which each animal has enough food to survive over a period of 12 days, in this interactive game from PLUM LANDING. Players see how the different species of plants and animals in a mountain ecosystem depend on one another. They also experiment with how changing the amount of one resource affects the whole ecosystem.

Take a field trip in your own backyard. Who shares that space with you? What do they eat? Where do they live? Backyard Wildlife, an original KET video, introduces children to animals they might find just outside the back door or in a nearby park. This video is available in both English and Spanish audio, along with corresponding closed captions.

From Seed to Fruit takes children through the different stages of growth in the life of a cherry tomato plant. Planting a seed in a cup and watching it grow over time is a wonderful way to introduce the life cycle to young children.

In this animated video from PLUM LANDING, Oliver is bummed to discover that when you dump your trash, it doesn’t just go “away,” it goes to an actual place. In Oliver’s case, that “place” is a river. (But with some double-strength garbage bags and a trusty Jetpaxx, Oliver just might save the day!)

Students build a simple model of a landscape to see how water droplets flow and how the shape of the land helps collect water, in this video from PLUM LANDING. By adding materials such as food coloring or paper to their landscapes, they also see how water carries pollutants.

In this Dinosaur Train clip, Dr. Scott the paleontologist discusses oceans and how they change over time. He explains that land that gets flooded can sometimes turn into an ocean, and that an ocean that dries up can turn into a desert.

Marine debris is anything in the ocean that's solid, made by humans, and not supposed to be there. From specks of plastic to large, abandoned boats, anything can become marine debris. Plastics are the most common types of marine debris, but rubber, cloth, glass, metal, and paper litter make up ocean trash, too. Marine debris is one of the biggest pollution problems threatening oceans and waterways today.

Unless people change the way they consume and dispose of products, the marine debris problem will continue to get worse. Plastic is one of the main types of ocean trash and hurts the environment, the economy, and health. For example, plastic bags can sink to the seafloor and suffocate coral reefs, a littered beach can mean lost tourism dollars, and people can get sick by eating fish contaminated with plastic particles. By working together, people can design solutions that prevent trash from entering the ocean in the first place. Cities, businesses, communities, homes, schools all over the world and you can all contribute to the ultimate solution: prevention.

Splash takes his pals to go see his friend, Lu, a fearless explorer in the deep. He has met Lu in his travels, and she has been an inspiration for Splash. Lu turns out to be a female football fish (the "Lu" stands for "bio-LU-minescent") who leads them on an adventure in the abyss.

Have your class learn along with Splash and friends in this lesson plan that accompanies the Splash & Bubbles story segment "Lu the Explorer." Teach about ocean zones and biodiversity in this lesson aimed at grade 1.
